The Under Armour Fat Tire 2 is a great improvement on its rugged predecessor with a sleeker profile. The one-piece bootie construction with the Boa® Closure system helps keep a locked-in fit while keeping the elements out. Runners will continue to benefit from the full-length Charged cushioning midsole and the Michelin® WildGripper outsole that provides impressive traction and comfort against even the toughest terrain. Large reflective pull-tabs at the front and back of the ankle provide a quicker way to pull the shoe on and off and increases visibility in low-light conditions.
